Shaft flex makes no difference in delivering distance. Meaning if you have the same weight of shaft on different flex and maintaining the same total weight.

The only variable is dispersion and the preference of tempo.

i recently fitted a LPGA tour player who also asked me to verify a specific club in her bag. She has a 3 wood which she trust and hits it 240 to 250 yards. Everyone on tour including her close friends commented that it is the wrong choice of shaft. So we started out by getting her to hit about 3 random shots on trackman...good numbers. then i proceed to ask her to play different shots, high left, low right, high right, straight stinger and just a baby fade. She hits them perfectly without even having to do a retake.

The answer was simple - keep the Cally 3 wood deep on the Diamana WB (first Gen) in 73 X in the bag. For good measure, we also built a similar specs as a backup in 73 S (2 inch tipped) in case she needs to play moonshoots particular on the superfast greens in the US.

1. The shaft is the engine of the golf club2. The shaft is the most important component of the golf club3. The letter flex code on the shaft tells me how stiff the shaft is4. The shaft is a key element for the amount of backspin imparted on a shot5. How a shaft plays and performs for one golfer or group of golfers is important for other golfers to know to be able to make a proper shaft selection decision6. The more expensive a shaft, the better it is7. The flex of the shaft has a very important effect on shot performance for all golfers8. The higher the clubhead speed of the golfer, the stiffer the shaft should be9. The right shaft adds distance by “kicking faster” through the ball10. How a shaft performs for a golfer(s) is an indication of its quality

Now with all the valuable inputs, don't we all just need this: http://golf.sevendreamers.com/ Experiencial travel at its best. Still saving for my spare 120k for that. Hopefully by then I will grow wiser.
